[RFC PATCH 00/23] at91: Replace duplicate device initialisation code with common code

[Ryan Mallon]

Each AT91 variant (AT91RM9200, AT91SAM9260, etc) currently has its own
devices file, which includes the MMIO address, interrupt
configuration, GPIO setup, etc for each device. This results in a large
amount of duplicated code.

This patch set introduces a framework for adding shared devices for the
AT91 platform and replaces the multiple device setup implementations for
each device with single implementations in the new framework. This has
a net reduction of nearly 5000 lines of code.

Each of the arch/arm/mach-at91/*_devices.c files becomes a collection of
structures (with some initialisation callbacks where necessary) with a
table of devices which are present on the particular AT91 variant. All
structures/functions are marked as __init/__initdata so there is little
additional memory overhead. This also means that the #ifdefs around each
device can be removed from the *_devices.c files (but remain in the new
common devices.c file) without overhead.

I have build tested the patch series for all of the  AT91 variants 
and devices, and have boot tested it on the AT91SAM9260 (Snapper 9260
board) and tested basic device functionality.
